1) An 18-year-old runner can complete a 10.0 km course with an average speed of 4.52 m/s. A 50-year-old runner can cover the same distance with an average speed of 4.07 m/s. How much later (in seconds) should the younger runner start in order to finish the the course at the same time as the older runner? s 2) A sprinter explodes out of the starting block with an acceleration of +3.8 m/s2, which she sustains for 1.4 s. Then,...
a skier starting from rest down a snow slope that makes 18 degrees with the horizontal. He starts from the height of 8 m. at the bottom of the slope is a 9 m long rough horizontal surface. the acceleration slowing the skier down on the rough patch has a magnitude of .8m/s2. what is the skier's speed when he reaches the end of the rough patch? calculate the time intervals it takes the skier to reach the bottom of...
A snowboarder on a slope starts from rest and reaches a speed of 1.7 m/s after 6.5 s. (a) What is the magnitude of the snowboarder's average acceleration? (b) How far does the snowboarder travel in this time?
Starting from rest, a person pedals a bicycle such that the angular acceleration of the wheels is a constant 1.40 rad/s2. The bicycle wheels are 35.0 cm in radius. What is the magnitude of the bicycle's linear acceleration (in m/s2)? What is the angular speed of the wheels (in rad/s) when the linear speed of the bicyclist reaches 11.6 m/s? How many radians have the wheels turned through in that time? How far (in m) has the bicycle traveled in...
A skier starting from rest skis straight down a slope 50 meters long in 5 seconds. What is the magnitude of the acceleration of the skier? How would you go about solving this type of question?
5. A car starting from rest moves in a straight line with a constant acceleration of 1.90 m/s2 for 14.0 s, then slows down to a stop with a constant deceleration of 2.60 m/s2. How far does it travel? X Blank meters 7. A ball is thrown vertically downward from the edge of a bridge 25.0 m high with an initial speed of 18.0 m/s. The ball falls all the way down and strikes the water below. Determine the time...
5. A car starting from rest moves in a straight line with a constant acceleration of 2.20 m's for 100 s,then slows down to a stop with a constant deceleration of 3.05 m/s. How far does it travel? meters 6. Two cars are traveling along a straight road. Car (A) maintains a constant spoed of 900 kmh: car (B) maintains a constant spoed of 101 km/h.
